A team of scientists claim to have discovered a new colour that no human has ever seen before. The research follows an experiment in which researchers in the US had laser pulses fired into their eyes. By stimulating specific cells in the retina, the participants claim to have witnessed a blue-green colour that scientists have called "olo", but some experts have said the existence of a new colour is "open to argument". The findings,published in the journal Science Advanceson Friday, have been described by the study's co-author, Prof Ren Ng from the University of California, as "remarkable". He and his colleagues believe that the results could potentially further research into colour blindness. Prof Ng, who was one of five people to take part in the experiment, told BBC Radio 4's Today programme on Saturday that olo was "more saturated than any colour that you can see in the real world". "Let's say you go around your whole life and you see only pink, baby pink, a pastel pink," he said. "And then one day you go to the office and someone's wearing a shirt, and it's the most intense baby pink you've ever seen, and they say it's a new colour and we call it red." During the team's experiment, researchers shone a laser beam into the pupil of one eye of each participant. There were five participants in the study - four male and one female - who all had normal colour vision. Three of the participants - including Prof Ng - were co-authors of the research paper. According to the research paper, the participants looked into a device called Oz which consists of mirrors, lasers and optical devices. The equipment was designed previously by some of the involved researchers - a team of scientists from UC Berkeley and the University of Washington, and updated for use in this study. The retina is a light-sensitive layer of tissue at the back of the eye responsible for receiving and processing visual information. It converts light into electrical signals, which are then transmitted to the brain via the optic nerve, enabling us to see. The retina includes cone cells, which are cells responsible for perceiving colour. There are three types of cone cells in the eye - S, L and M - and each one is sensitive to different wavelengths of blue, red and green respectively. According to the research paper, in normal vision, "any light that stimulates an M cone cell must also stimulate its neighbouring L and/or S cones", because its function overlaps with them. However, in the study, the laser only stimulated M cones, "which in principle would send a colour signal to the brain that never occurs in natural vision", the paper said. This means the colour olo could not been seen by a person's naked eye in the real world without the help of specific stimulation. To verify the colour observed during the experiment, each participant adjusted a controllable colour dial until it matched olo. Some experts, however, say the new perceived colour is a "matter of interpretation". Prof John Barbur, a vision scientist at City St George's, University of London, who was not involved in the study, said that while the research is a "technological feat" in stimulating selective cone cells, the discovery of a new colour is "open to argument". He explained that if, for example, the red cone cells (L) were stimulated in large numbers, people would "perceive a deep red", but the perceived brightness may change depending on changes to red cone sensitivity, which is not unlike what happened in this study. But the study's co-author Prof Ng admitted that although olo is "certainly very technically difficult" to see, the team is studying the findings to see what it could potentially mean for colour blind people, who find it difficult to distinguish between certain colours.

TruthLens AI Summary
A groundbreaking study by a team of scientists has reportedly led to the discovery of a new color, referred to as 'olo', which no human has ever seen before. The research involved an innovative experiment where participants had laser pulses directed into their eyes, stimulating specific cells in the retina. This unique approach allowed the participants to perceive a blue-green color that had not been previously recognized. Prof. Ren Ng, a co-author of the study from the University of California, described the experience as remarkable, stating that olo appeared to be more saturated than any color typically visible in the real world. He provided an analogy to illustrate this phenomenon, comparing it to seeing a more intense version of a familiar color, suggesting that this new color could offer insights into color perception and potentially aid in research related to color blindness. The findings were published in the journal Science Advances, igniting discussions within the scientific community regarding the validity of the claim of discovering a new color.
During the experiment, five participants with normal color vision were involved, with the apparatus designed to selectively stimulate M cone cells in the retina, which are responsible for processing green hues. This selective stimulation means that the color olo, while perceived by the participants, could not be seen in natural conditions without the specific laser intervention. Despite the excitement surrounding the discovery, some experts express skepticism about labeling olo as a new color, suggesting that the perception of color can be subjective and influenced by various factors. Prof. John Barbur, a vision scientist who did not participate in the study, emphasized that while the research represents a significant technological achievement, the classification of olo as a new color is debatable. He noted that the perception of colors can vary greatly depending on the stimulation of different cone cells and their sensitivities. The research team, however, remains focused on exploring the implications of their findings, particularly in relation to improving the understanding of color blindness and how individuals with this condition perceive colors differently.
TruthLens AI Analysis
The discovery of a purported new color, referred to as "olo," has intrigued both the scientific community and the general public. This news article reports on a study conducted by researchers who claim to have found a color that no one has ever seen before, based on an experiment involving laser pulses directed into participants' eyes. The implications of such a discovery, if proven valid, could be significant, particularly in the fields of vision science and color perception.
Scientific Credibility and Skepticism
The article highlights a mix of excitement and skepticism surrounding the discovery. While Prof. Ren Ng describes the new color as "remarkable" and potentially useful for further research into color blindness, other experts remain cautious, suggesting that the existence of a completely new color is debatable. This dichotomy of views raises questions about the study's methodology and the validity of the findings. The use of lasers and the specific conditions under which participants viewed the color may not adequately represent how colors are perceived in everyday life.
Public Perception and Interest
The news aims to capture public interest by presenting the concept of a "new color," which is inherently fascinating. Such claims can evoke curiosity and wonder, encouraging discussions about human perception and the nature of reality. It might also inspire individuals to think about their own experiences with color and how they perceive the world around them.
